BzzAgent Jono sent us a BlenderBottle to try.  I cannot say enough about this product.  My 11 year old son and I both use it daily at our house.  Our favorite thing to use it for is to make protein shakes.  We take a scoop of Jay Robb or some similar protein powder and mix with 8 oz of unsweetened vanilla or chocolate almond milk.  It equals oh so yummy goodness.  Use the BlenderBottle to measure the ounces along the side of bottle.  At the bottom of the cup is a spring ball.  You, then, scoop in the powder and shake the bottle to your hearts content.  The spring ball mixes it all up.  How easy is that!  The clean up is way easier then if you would use a blender.  Just place the BlenderBottle in the top rack of your dishwasher or hand wash it.  You can use it to make salad dressings or pancake batter, too.  We give it 5 stars by far.  And, if you are in the Owatonna area you can purchase your very own at Dow Chiropractic or Cashwise Foods.
